What are the Purchase Limits for Weed in Each State?

On February 2, 2022, Mississippi became the 37th state to grant medical access to cannabis, while 18 states and the District of Columbia also offer cannabis for adult use. Unfortunately, each of these areas have slightly different rules regarding how much cannabis patients or caregivers can purchase at a given time, or in a given period of time.

Purchasing limits are implemented to prevent consumers from stockpiling large quantities of cannabis presumably for resale into black markets, but dispensaries also track this information for compliance with state regulatory commissions. 

States with medical programs register each sale to the corresponding patient for a comprehensive paper trail, and many states with recreational sales use a system called METRC, or Marijuana Enforcement Tracking Reporting and Compliance, to keep track of sales and stock for state reporting.

Consumers can be forgiven for being wary of this data-collecting, but recreational sales do not track personal information, and the data that is collected is used primarily for compliance, and sometimes for marketing purposes. However, many states, like California, also have laws offsetting this data, including limits on how long the data can be stored.

Some states with both recreational and medical programs offer different purchasing limits for adult users and medical users. Purchasing limits are measured by ounces (oz), grams (g), fluid ounces (fl oz), or milligrams of THC (mg).
